To all'fwhom it may concern.'

Be it knovm tha-t I, INILLIILM H. CmAK., a citizen of the United States, rcsidin in the city and county of Philadelphia, tate of Pennsylvania, have invented a and useful Train-Pipe Coupling, .of which the followin Y is a specieation.

ily invention nelates to :a new and :useful train-pipe coupling which is adapted to automatically connect the ilu-id pipes of cars when they lare brought together.

It further consists in providin a reciprocating valve for the coupling writ :means im' actuatin the same.

It furt Ier consists of .providing .a casing or closure -for the operating arts.

It further consists of o er novel details of construction, all as will be hereinafter fully set fort-h.

Figure 1 represents aside elevation of -a 'car showing the `train-,pipe coupling in position. Fig. 2 represents an end view thereof with the .car portion omitted. Figs. 3 and 4 represent -partial elevations and partial sectional views, on an enlarged scale, in different positions. Fig. 5 represents a sectional view showing the position .of the valve Within the lungcr.

Similar numera of reference indicate correipond-ing parts in the figures.

eferring to the drawings: In the connecting ci `the air or steam pipes of'a train it is necessary, in order that this can be done 'autoniatically, to provide means which will be brought into proper alinement when the oars are brought together, and which will provide some means for automatically operati-nga valve or stop to permit the flow `of the steam or air through the connection at the proper time. In the drawings I have accomplishing this purpose and which embodies my invention, but it will be evident that the arrangement of the parts may be varied.and other instrulnentalities may be employed, which will come Within the scope of my invention and I do not therefore desine to be limited in eve instance to .the caract construction as herein shown and described, but desire to make such changes as may be necessary. r

In :the drawings I have shown t-Wo -coupling members l but it will beevident that any number may be employed and as. the description of one oit these members -Will serve for sho-Wing the parts all I have deemed it unnecessary to describe but one.

I l designates a portion of the car having a draw-head 2 to which I preferably secure hang/ers 3 and 4. Connected with said hanger in any; lsuitable manner, in the present instance. y mea/ns of bolts, are the casigs 5 and 6, although but a single casing ma be employed it desired. Secured to sai casings `5 and 6 are the frames 7 and 8, to each of which I secure a pipe 9,eachhaving a coupling member 1.0 upon one end, to which is adapted gto be secured .the steam or air; ipe 11 sho-Wn in dotted lines Fig. l.4

,Dfovabl mounted in .each f the casings .5 and 6 'm e plunger 12, the same having a head 13 thereon .to which is attached -a Stung box 14, which receives and moves u n the pipe .-9, it being understood that said .unger l2 vsuitably its an opening at the roerend of the casing 5 and .that said plunger is provided with a lug which iits the casing 5 and forms .a shoulder 15, between which and the end of the casing 5 is seated a spring 16 for said plunger in its normal position. The p Unger 12 is provided with a suitable bore 1.7 .and has formed on. its inner wall a valve seat 18 and said lunger prol'ects a sui-table distance beyond t e outer e ofthe casing .5 and is provided with a flange 19 adjacent its end. Suitably` secured to said flange is an elastic casing 20 which is formed of any suitable material, such as nubber and which has a slightly rounded outer wall orend 21. Preferably carried by thesaid outer wall of the said elastic casing 20 is a head 22 which is provided with the rounded portion23 adapted to be ser. formed recess in the head of a valve in 24, said valve in being suitably movab e and uided in t e bore l1710i the plunger 12 ,and t le end of saidvalve pin being adapted :to abut the stem 25 of the valve 26, whilea reinst the inner end of said valve .there is a spring 27 Which tends to normally hold said valve against its seat 18, the 4other end of said spring 27 abutting a suitable stop, in the present instance a pipe 28, which is fitted -Wrthin the bore 17 oflthe plunger 12 and is Amovable therewith. Bearing upon the plunger 12 and seated Within the elastic casing 20 is a s ring 29 which is adapted to normally hold e said elastic casin extended in the position seen in Fig. 3, tiat is to say, with the end .of the elastic casing a suitable distance from the end Aof the plu-nger 12. c

The loperation ,of the parts justI descmbed will be appanentw-The parte bemg .in the ted a correspondingly position seen in Fig. 3, the valve 26 is seated upon its seat 18 so that no passa e of the air or steam can pass or escape t rough the coupling, but when two cars are brought together for the purpose of coupling the end of the coupling, upon one will abut the end of the couplin upon the other car, that is to say the curve heads 21 will be brought toether and as the casing 20 is elastic, it will Ee suitably compressed, overcoming the tension of the spring 29 and moving in the head 23 with the valve pin 24, it being understood that the curved faces between said head 23 and the valve pin 24 permit of a certain amount of lateral movement of the parts. The forcing of the valve in 24 moves inwa`rdl)T the valve 26 removing the same from contact with its seat, against the-tension ot the spring 27 and as the cars continue to be brought together to the proper oint the plunger 12 will be moved inward T against the tension of the main spring 16 until the parts assume the position seen in Fig. 4, when the air or steam can pass through the coupling as desired. As soon as the cars are uncoup ed the spring 27 returns the valve to its normal position while the elastic casing 2() is expanded by the action of the spring 29. At the same time the main spring 16 returns thebplunger 12 and its parts to their normal position. In some instances it may be desirable to connect the coupling vwith the air hose in another manner and in order to permit of this I have provided the pipes 30 and 31 which are connected on opposite sides of the device with the plunger 12 and which are movable in slots 32 in the sides of the casing 5, said pipes 3() and 31 having a coupling 33 having air hose 34 connected therewith, which isgon the car, so that when the parts are operated, as before described, the air will pass through the coupling device. By this means it will be seen that the air can pass through the lpipes 30 and 31 when the valve is unseated f the coupling of the cars and can ass through the train system as desired. `lie valve 26 which I have shown is of thc reciprocating style and I have shown the same formed with the grooves or passages 35 in the side walls to permit of the passage of the fluid therethrough when the valve is unseated.

Attention is called to the fact that the valve pin 24 is provided `with a head orA shoulder 36 which is so arran ed as to abut the end 37 of the plunger w en the valve pin 24 is moved in by the coming together of the cars for coupling purposes. .By this means it will be seen that further inward movement of the valve 26 in the plunger is prevented and the entire pressure is removed om the sides of the elastic casing 20 and is applied Vto the plunger 12 which is moved inwardl thereby compressing the spring 16. From t 's it will be understoodthat the casing 6. n a device of the `valve pin 24 serves not only to actuate the valve 26 to unseat the same but further acts on the plunger to move the same and in ich it is guided.
